Cold-rolled steel coil inner ring automatic spot welding machine and using method thereof

Abstract

The invention relates to the field of unwinding or uncoiling of metal lines, metal strips or other flexible metal materials, in particular to a cold-rolled steel coil inner ring automatic spot weldingmachine and a using method thereof. The cold-rolled steel coil inner ring automatic spot welding machine comprises a spot welding machine component (1), and is characterized by further comprising a X-direction moving vehicle component (2), a Y-direction moving vehicle component (3) and a Z-direction moving vehicle component (4), and the like, wherein the spot welding machine component (1) comprises an inner ring open-circuit reaming device (101), an inner ring tensioning device (102), the spot welding machine (103), a transmission main shaft (107), a synchronous belt driven wheel (109), a synchronous belt driving wheel (110) and the like. The using method of the cold-rolled steel coil inner ring automatic spot welding machine is characterized by comprising the following steps of (1) identifying; (2) moving; (3) stretching; (4) supporting; (5) detecting; (6) welding; and (7) repeating. The cold-rolled steel coil inner ring automatic spot welding machine is high in automation degree, safe and reliable.

Description

technical field [0001] The invention relates to the field of unwinding or uncoiling of metal wires, metal strips or other flexible metal materials, in particular to an automatic spot welding machine for the inner ring of cold-rolled steel coils and a method for using the same. Background technique [0002] In the cold rolling processing production line of the metallurgical industry, the inner ring of the semi-finished cold rolled steel coil often sags to a certain extent. Once this happens, during the hoisting process of the steel coil, or when entering the next process, the inner ring may become loose or the steel coil cannot be loaded into the reel of the uncoiler, resulting in the failure of the automatic operation of the unit. The current countermeasure is to manually arrange the inner ring and clamp it with a clip near the head, or use a hand-held welding device to weld and fix it. There are following problems in this way: [0003] 1. The automatic fixation of the inn...

AI Technical Summary

Problems solved by technology

[0003] 1. The automatic fixation of the inner ring cannot be realized, which is inconsistent with the current production requirements of "unmanned and less humanized", which restricts the improvement of production rhythm

[0004] 2. Temporary fixation with clips is unreliable, and new tape heads will sag during lifting or rolling

[0005] 3. Manual fixation is adopted, which needs to be operated offline, which increases additional labor costs

The output of the unit is large, the number of steel coils per day is large, the workload of the workers is particularly heavy, and the labor safety of the operators cannot be guaranteed
